Abstrakt
As yarns control the ultimate failure of fiber reinforced composites, mechanical behavior warrants much
consideration. The present study focuses on the experimental and simulation analysis of the tensile
fracture behavior of twisted yarns. A quasi-fiber scale model of twisted yarns made of HMWPE fibers
is established using virtual fibers. The tensile fracture behavior of twisted yarns is simulated using a
maximum stress criterion with a random distribution of properties. The tensile fracture loads of six kinds
of twisted yarns agree well with the experimental results. The numerical precision and dispersion of the
proposed method are analyzed systematically. The influence of damage factor and displacement at
failures on the simulation results of twisted yarns are also obtained. Above modeling and analysis
method provides a helpful tool for understanding the yarn architectures of fiber reinforced composites.
